In the past twenty years continued interests have been focused on adiabatic rapid population transfer and coherence in atomic or molecular system. The stimulated Raman adiabatic passage process has been intensively studied experimentally, analytically, and numerically.

近二十年来，随着科学研究的不断进步，人们对运用绝热快速通道控制原子或分子的布居数和相干性产生了较大的兴趣，并运用受激拉曼绝热过程进行了数值模拟、实验和分析。

The main contributions are as follows:(1) The decoherence suppression of N level Markovian systems is investigatedby the optimal control in the coherence vector representation. The N level Markoviansystem can be described by the master equation, and possesses a standard bilinear formin the coherence vector representation.

本论文利用密度矩阵相干向量表示研究了退相干效应的抑制和相应的纠缠控制问题，论文主要工作包括：(1)在密度矩阵相干向量表示下，利用最优控制研究N能级Markov系统的退相干抑制问题。N能级Markov系统可以用主方程模型描述，在相干向量表示下具有标准的双线性形式。

It is found that the size of vortex dark core in the focal region and the spectral degree of coherence in the focal plane depend on the topological charges n , interceptive parameters δ, relative coherence lengths σg and the parameters α.

数值计算结果表明，涡旋暗核的大小和焦平面上的光谱相干度都取决于入射光的拓扑电荷n、截断参量δ、相对相干长度σg和参量α。

Therefore, a revised model of the correspondence view is proposed. It compares textual cohesion and textual coherence in terms of etymology and acceptation, research subject, device and function. A conclusion is reached that cohesion and coherence are two interdependent semantic relations that work at different levels within a text and interact with each other to create textuality.

该模式从语源和语义、研究对象、具体手段和功能等四方面对篇章的衔接和连贯进行了对比，结论认为衔接和连贯是篇章中固有的两种语义关系，都有各自的实现手段，分别在篇章的微观和宏观层次上起着连接篇章成分的作用，相互影响作用，共同赋予篇章以篇章性。

We establish the quantum theory of the one-mode micromaser injected by ultracold V-type three-level atoms with atomic coherence, and discuss the properties of the emission probability, the photon statistics, the spectrum and the velocity selection. We find the following results. There are two sets of peaks in the plot of the emission probability versus the cavity length. The injected atomic coherence can deeply affect the values of the two sets of peaks and the unresonant platform.

第一部分包括第一章到第四章，在这部分，我们建立了具有原子相干性的超冷V型三能级原子注入的单模Micromaser的量子理论，研究了原子发射几率、腔场光子统计、腔场光谱、以及腔对原子速度选择等性质，并着重研究了原子相干性对这些性质的影响。

For the mechanism of imaging radar, it is inevitable that the coherence speckle advents. We also bring the method of median filtering into image process in order to eliminate the impacts of coherence speckle noise.

成像雷达由于成像机理的原因不可避免地会引入相干斑噪声，因此直接利用SAR图像进行处理会导致过多的虚警发生，为了减少相干斑的影响在对SAR图像处理的同时引入了中值滤波，因此在很大程度上消除了SAR图像中的噪声干扰。

It contains"coherence after break"、"coherences and breaks"、"repeatment after break"and"no coherence after break".

论文写作采用了语言体系理论、语义范畴理论、认知心理理论。

SS患者腮腺导管病变存在广义的一致性和狭义的不一致性。

Visual evoked potentials of twelve healthy volunteers were recorded under two conditions including normal state and one night's sleep deprived state, and were wavelet transformed to time-frequency values between 30 to 60 Hz. The inter-trial phase coherence of prefrontal lobe and the evoked response phase coherence between prefrontal lobe and occipital lobes were calculated.

在正常状态和一夜睡眠剥夺状态下提取12名受试者的视觉ERP，进行30~60 Hz的小波变换，以此计算前额叶区域的导联内相位相干，以及枕叶和前额叶之间的相位相干性。
